While it includes the same number of microphone positions, and many of the same features, there is a key difference outlined below. The microphone configuration is designed for solo instruments, as opposed to a full orchestra.

Instead of the surround and vintage surround microphone positions used in the Hollywood Orchestra series, the Hollywood Solo Cello supplements the close and mid microphone positions with vintage alternatives.

These extensive libraries were recorded, engineered, and produced with the superior level of sound quality the EastWest brand is known for. Each of the instruments was recorded in Studio 1 at EastWest Studios, the same studio Hollywood Orchestra was recorded in. This gives the complete Hollywood Orchestral series a consistent sound and ambience, which emulates a traditional large studio orchestra.

A wide variety of articulations were recorded for each instrument, focusing on typical solo instrumentation. In some cases, these various articulations are presented as separate instruments in Play's Browser view. In other cases articulations are accessible via a key-switch instrument, where multiple articulations load as one instrument, and pressing a trigger key activates the current one.
